IMPROVEMENT IN LUBRICATORS.

Specification forming part of Letters Patent No. [80,925, dated August8, 1876; application filed May 22, 1876.

To all whom it may concern:

Be it known that I, JOSEPH W. REED, of Kalamazoo, in the county ofKalamazoo and State of Michigan, have invented a new and ImprovedLubricator, of which the following is a specification In theaccompanying drawing, Figure 1 is a'vertical longitudinal section of myimproved lubricator, taken on the line X X, Fig. 2 and Fig. 2 is a sideview of the same, with part broken off to show the'interior.

Similar letters of reference indicate correspondin g parts.

My invention relates to a double automatic lubricator forsteam-cylinders of locomotives and other engines, by which one of thelubricators may be dispensed with and it consists of a cup cast in onepiece with fixed internal feed-pipes, having regulating top nozzles andouter cooks for shutting off the steam.

In the drawing,- A represents the cup of my improved lubricator, whichis fastened to the top of the boiler, back of the smoke-stack. The cup Ais connected, by steam-pipes B at opposite sides of the cup, with thesteam-chests of the cylinder. Each pipe B has a stop-cock, B, at theoutside of the cup, by which the steam-connection may be shut off incase one side of the engine breaks down. The feedpipes G at the insideof the cup are made in one casting with the body of the cup,.andextended from the exit-points, at opposite sides, in an upward curve, tosome distance from the cup A. The upper ends of the feed-pipes areplaced sidewise to each other, and provided. with regulating-nozzles D,that are screwed into the feed-pipes, so as to be set conveniently asmall distance (about oneeighth of an inch, more or less) from the cup.

The casting of feed-pipes and cup in one piece makes the cup cheaper,and without joints. The connecting-pipes B are screwed from the outsideinto the feed-pipes (J. The steam passes up the pipes from thesteamcylinder, and condenses gradually in the cup, which, by the doublecondensation of the pipes forces the oil up the nozzles and down thepipes as long as the engine is running. When the steam is shut ofl, thesupply of oil is interrupted, being regularly supplied when the steam islet on again.

The cup A is readily unscrewed for filling, and the lubricator cleanedby blowing out from below, a bottom stopcock and pipe-connection withthe boiler admitting the required steam.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is

1. The combination of the lubricator, having interior feed-pipes, withcylinder connecting-pipes and stop-cocks at opposite points, to shut offeither pipe, substantially as herein shown and described.

2. A lubricator having the feed-pipes cast in one piece with the body ofthe cup, substantially as herein shown and described.

3. The combination of the interior feed-pipes with adjustable topnozzles and the cap of the lubricator, to regulate oil-supply,substantially as herein shown and described.
